SPERM1 Flashcards
spermatogenesis
semineferous tubules
epididymis
sperm maturation
dectus deferens
propel sperm to ejaculatory duct
seminal vesicle
provides nutrients for sperm and fluid
prostate glands
provide enzymes and proteins for coagulation and liquefaction
bulbourethal gland
add alkaline mucus to neutralize prostatic acid and vaginal acidity
reasons for seminalysis
fertility testing, post-vasectomy seminal analysis, forensic analysis
most common cause of infertility
variocele
sperm head of variocele
tampered
semen composition of spermatozoa
5%
sperm composition of seminal fluid
60-70%
sperm composition of prostatic fluid
20-30%
sperm composition of bulbourethal gland
5%
methods of collection
masturbation method, condom method, coitus interrupts
best method for collection of sperm
masturbation method
condom method used
non-lubricant, polyurethene condom
In specimen collection, sexual abstinence period must be
not less than 2 days or not more than 7 days
prolonged abstinence lead to
high volume, low sperm motility, high flavin( grayish appearance)
First portion is missing to ejaculate
low sperm count, high pH, specimen will not liquify
last portion is missing to ejaculate
high sperm count, low pH, specimen will not clot
If collected at home, specimen must be kept at _____temperature and delivered to the lab within _____________
37 DEGREES C,1 hour
Specimens that don’t liquefy must be treated must be treated with
amylase, bromelain, alpha-chymotrypsin
For fertility testing, the sample must be: and the result must be:
Strasinger (6): 2-3 sample; not less than 7 days, not more than 3 weeks apart
Strasinger (5) 2-3 sample;2 weeks interval
Result: 2 abnormal samples= significant
appearance of sperm
grayish-white, translucent, musty brown/bleach odor
result of appearance of sperm
Infection: white turbiidty
rbc/brown color: increased rbc
yellow color: urine contamination, medication, high flavin
volume of sperm
2-5 mL
results of volume of sperm
increased: abstinence
decreased: infertility
viscosity
normal droplets
result of viscocity
increased: low sperm motility
abnormal: threads (2cm long)
reporting: 0-watery
4-gel like
pH
7.2-8.0
result of pH
increased pH: infection
decreased pH: increased prostatic fluid

sperm motility grading: slower speed,some lateral movement, b
3.0
sperm motility grading: rapid, straight line motility
4.0
sperm moving linearly or in a large circle
PM (progressive motility)
sperm moving with an absence of progression
NP(non-progressive motility)
no movement
IM (immotility)
NORMAL QUALITY

normal values for sperm morphology (Kruger’s strict criteria)
> 14%
stains in order to view sperm morphology
papanicolaou stain (preferred), wright’s stain, giemsa stain
abnormal sperm viability
decreased (↓) motility, BUT normal count
stain used in modified bloom’s test
eosin-nigrosin stain
microscope used in modified bloom’s stain
bright field microscopy
phase-contrast microscopy

dead sperm
INTERPRETATION OF MODIFIED BLOOM’S STAIN: bluish white(unstained)
living sperm
50% or 75% living sperms
normal
↓ or absent of fructose
↓ sperm concentration
screening test result for seminal fluid fructose
Resorcinol test/Seliwanoff’s test
test result: positive fructose in seminal fluid fructose
orange color/red-orange
concentration of seminal fluid fructose
≥ 13umol/ejaculate
anti-sperm antibodies occur in both women and men; and can be detected in:
semen, cervical mucosa, serum

collected in patient’s home)

_______it can be preserved in frozen
state and stored for one year at –85 °C (seminal banks)
ARTIFICIAL INSEMINATION
Detects presence of IgG antibodies
Reagent: AHG + latex particles or treated RBC coated with IgG
Mixed Agglutination Reaction (MAR)
reagent of MAR
AHG + latex particles or treated RBC coated with IgG
